Behold the "Merb'ys"—a breed of Canadian bearded mermen flapping their fur and fins for a good cause. The gentlemen of Newfoundland and Labrador Beard and Moustache Club are posing in nowt but their merman garb for a dudeoir-style calendar to raise money for mental health organisation Spirit Horse NL.The Merb'ys are thus-named because "the Newfoundland mermen are a different breed," says Hasan Hai, founder of the beard and moustache club.

"It basically uses horses to provide equine therapy for people with mental illness, people who want to live better lives, people with physical limitation," Hai told.

Donning a fin was a challenge for the men during the calendar shoots. "Moving around in a fishtail is not as easy as you would think," Hai continued, adding that there was "a lot of hopping" and squirming involved behind the scenes.
